Abstract:
According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40° C. and 100° C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.
